I guaranteed to compose something about the ACSM seminar in Denver as well as then lack of time did the rest….and never got around composing anything.
So, with a bit of time offered I will compose few reflections about the conference.
The topics covered in the sessions were rather diverse as usual, ranging from obesity to armed forces medicine to sport performance as well as there were tons of parallel sessions which makes it impossible to comply with whatever happening. I will provide few notes on the ones I attended, however my general perception of the seminar was that sport performance research study is ending up being more as well as more unusual as well as there is a great deal of emphasis on exercise science clearly because of funding opportunities. Also, I sense a bit of staleness in the scientific neighborhood as I keep seeing a great deal of experiments repeated over as well as over once again as well as few ingenious approaches/ideas. I have discussed this topic on my article on “the Leader” newsletter, as well as will not replicate it here, however I sense that the disconnect between the lab as well as the field is getting bigger.
Nutrition in rehabilitation
Professor Kevin Tipton from Stirling university (http://www.sports.stir.ac.uk/staff/kevin-tipton.php) provided a great overview for the utilize of protein for muscle mass remodelling. Kevin composed a fantastic chapter in my book on stamina as well as conditioning as well as provided his work in a extremely elegant manner.
Some great evidence was provided on the unfavorable impacts of a reduction in energy intake when injured. This in fact, may be poor news as it may sluggish down muscle mass recovery. So nutritional advice for athletes in rehab should be carefully organized as while it is true that excess energy intake will lead to weight gain as well as alterations in body composition, it is likewise true that reducing energy intake as well much may sluggish down muscle mass remodelling.
He likewise suggested the utilize of Omega 3 Fatty acids to facilitate healing as suggested in recent papers from Bettina Mittendofer’s lab (http://www.ncbi.nlm.nih.gov/pubmed/21501117)
Professor Stuart Phillips provided likewise a great talk on protein metabolism as well as suggested the Omega 3 FA approach also (4g of FDA authorized Lovaza http://www.lovaza.com/). I am sure more research study will be published soon on the utilize of Mega 3 FAs for muscle mass remodelling.
Dr. Ferrando talked about a “Cocktail” of supplements showing fantastic promise (so not a single product) in his very-applied talk on exactly how to speed up healing complying with hip replacement. He suggested that in the genuine world we want to utilize all we understand from research study as well as apply it for our patients/clients. showed some data of reduced day in hospital utilizing a drink made from all compounds suggested to have advantageous impacts on muscle mass remodelling (e.g. creatine, proteins, Omega 3, etc etc).
New Techniques
Some extremely fascinating work was provided by Dr. Minoru Shinonara’s Lab. Dr. Shinonara is doing some work with a new ultrasound method able to quantify muscle mass stiffness http://www.ncbi.nlm.nih.gov/pubmed?term=%22Shinohara%20M%22%5BAuthor%5D%20and%20muscle%20stiffness
A extremely fascinating method as you can see here: http://www.supersonicimagine.fr/product_0_1_shearwave-elastography,en.htm
Overtraining
There was an entire afternoon session on overtraining.Consensus is that there is not a single marker, however a range of things which can be determined to assess if an private is at danger of overtraining or already overtrained. It was quite much a series of presentations of data already offered in the literature.
The most fascinating talk was from Dr. Bradley Nindl. In specific some new methods as well as some data just recently published:
Some practical data showing the impacts of extreme physical training in army recruits. This fascinating transdermal technique to determine IGF-1 complying with exercise. in addition to blood areas method to determine IGF-1.
Dr.Nindl talked about the idea of “fit to fight” which is extremely similar to the sport idea of readiness to train or compete.
Creatine
There was a great update on the condition of research study on creatine, which still is perceived to be a “bad supplement” in the media. However, the recent work from Kley et al 2011 clearly showed there are no problems with creatine supplementation.
Recent data show likewise a reduction in pain in muscle mass dystrophy with creatine as well as likewise that brain creatine can be increased from 4 to 9% with supplementation.
We do not understand well if it works in older adults; nevertheless basal brain creatine seems to be inversely associated to uptake. So the more you have, the less you are likely to gain with supplementation. recent work suggests the prospective utilize of creatinesupplementation for a range of pathological conditions indicating that more work on its impacts on the central anxious system will shed more light on other prospective uses.
Very fascinating recent work from my dear associate as well as buddy Dr. Christian cook has shown the prospective for creatine to counteract the unfavorable impacts of sleep deprivation.
Recent work on creatine security from Dr. Gualano was likewise mentioned here.
One of the speakers in this session mentioned the IOWA mishap (http://www.businessinsider.com/exertional-rhabdomyolysis-iowa-football-players-hospitalized-after-their-workout-2011-1), with recommendation to the public health and wellness report showing that Creatine had nothing to do with what occurred to the athletes. However, creatine was mentioned triggering the media to then speculate about the possible influence of creatine intake on the health and wellness of the athletes.
Muscle atrophy as well as sarcopenia
Good tutorial lecture from professor Marco Narici from Manchester Met. university (http://www.shs.mmu.ac.uk/staff_list/staffbiog/?StaffID=740). Marco provided a great overview of what occurs to muscle mass as well as tendon with immobilisation. He likewise showed data on concentric vs. eccentric packing as well as the impacts on muscle mass fascicles as well as tendon stiffness.
He showed that with immobilisation, muscle mass size decreased 0.4% per day! as well as you can lose about 2700 sarcomeres after 10 days of immobilisation. Some great data to keep in mind next time an athlete is in a cast!
Barefoot running
Possibly the most fascinating session of the conference. Some fantastic speakers as well as fantastic arguments/data to support barefoot running.
It was all produced by recent work from Lieberman (http://www.ncbi.nlm.nih.gov/pubmed/20111000). nevertheless when you look at the data carefully the obvious conclusions is that it needs to be introduced slowly with athletes as there are some dangers of injury. But, if the method is grasped might potentially be a fantastic techniques to enhance the muscles controlling the foot as well as the ankle as well as ultimately likewise lead to performance in addition to reduction of injuries.
One of the most fascinating data was the actual lack of evidence of effectiveness of running shoes in reducing injury risk. That is, there is not a single research study that has shown that shoes reduce the danger of injury. In fact, there is now evidence that the danger of injury is unchanged, perhaps even higher in the costly shoes. Injury rates haven’t come down even a bit bit since the 1970s, the period which has seen the explosion in the running shoe industry. Back in the 70s, the shoes look like today’s minimalist shoes, however about 70% of runners were getting injured, the exact same rate as today.
Russ Tucker has written a great evaluation of the session on his blog if you want to understand more about this issue:

Pacing as well as fatigue
Dr. Ross Tucker provided an elegant talk on exactly how the brain controls exactly how difficult you go during a time trial as well as exactly how it controls your pacing. more details on www.sportsscientists.com
I truly enjoyed the excellent work done by Dr. Markus Amman. I truly like his design to research study tiredness as well as if you want to understand more you should truly checked out some recent work published from his lab:
Amann M, Secher NH. (2010). Afferent comments from fatigued locomotor muscles is an important determinant of endurance exercise performance. J Appl Physiol, 108, 452-454.
Amann M, Secher NH. (2010). Point: Afferent comments from fatigued locomotor muscles is an important determinant of endurance exercise performance. J Appl Physiol, 108(2), 452-4; discussion 457; author reply 470
Prof. Romain Meeusen provided a great overview of the central elements of tiredness utilizing human as well as animal models.
However the highlight for me was Dr. Schneider from Germany.He provided some fascinating data on a new approach to EEG to research study human performance in a range of settings. His recent work on music as well as exercise is rather entertaining http://www.ncbi.nlm.nih.gov/pubmed/20845211 in addition to the link between exercising as well as neurocognitive function with astronauts http://www.ncbi.nlm.nih.gov/pubmed/21654620.
There was a great deal more going on with more than 6000 delegates going to the conference. however the above is what made it fascinating for me. It was of program a fantastic chance to catch up with old colleagues as well as buddies in addition to satisfy new people as well as discover more about the interesting work they are doing as well as the difficulties currently dealt with by academics in this field having a hard time to draw in considerable funding to conduct research study projects.
Unfortunately I will not be able to go tonext years’ seminar in San Francisco, however I hope to be able to make the 2013 annual seminar in Indianapolis.
